Prosecutors have subpoenaed records at six banks and financial institutions where a judge accused of demanding a $250,000 bribe holds accounts, The Post has learned.

A search of Judge Victor Barron’s Brooklyn Supreme Court chambers – locked since his Tuesday arrest on a bribery charge – turned up a check from one bank in his coat and records from another financial institution on his desk, sources familiar with the investigation said.

“We want to see if he has any money stashed or hidden somewhere,” one source said.

Barron was busted for allegedly taking $18,000 cash from a lawyer in exchange for signing off on a $4.9 million settlement in a personal-injury suit. The judge, who’s free on his own recognizance, has pleaded not guilty to a bribe-receiving charge.

When investigators went to search his Marine Park home, his wife couldn’t believe the allegations against her husband.

The district attorney’s office also is looking into whether Barron steered civil cases toward a close female friend – also a lawyer – and prompted other attorneys to fill in for her when she was running late for courtroom appearances, sources said.

Barron, 60, fancies himself as a ballroom dancer but liked to get down like James Brown at judicial functions, sources said. The dapper dresser was known to carry a “wad of cash,” court insiders told investigators.

The bribery charges stem from a personal-injury lawsuit filed by the family of an infant severely injured in a 1998 Brooklyn car crash.

Brooklyn DA Charles Hynes has said Barron allegedly refused to sign off on a $4.9 million settlement – from which lawyer Gary Berenholtz was legally entitled to $1.6 million in legal fees – unless the lawyer paid off the judge.

Barron was busted after allegedly accepting $18,000 in cash earlier this month from Berenholtz, who was working with authorities by then, Hynes has said.

The family of the infant crash victim – who court records show was left blind, nearly deaf and severely brain-damaged as a result of the accident – was appalled that Barron allegedly tried to cash in on their misfortune, according to one source familiar with the case.

“What could be more repulsive? They’ve been put through enough and now they have to be put through something else?” the source said. “It’s a child who’s severely brain-damaged.”
